A photoacoustic calorimetric study of horse myoglobin.
The dynamics of the enthalpy and volume changes for the photodissociation of CO from horse myoglobin has been studied by time-resolved photoacoustic calorimetry which measures the dynamics of enthalpy and volume changes on the nanosecond time scale. The role of the Lys 45 salt bridge in the ligand dissociation is discussed.
